RAILWAY-TRACK.

T0 all whom tim/ay concern.'

Be it known that I, JOSEPH P.. MARois, of the city of Montreal, in the'Province of Quebec and Dominion of Canada, haveinvented new and useful'VImprovements lin Railway-Tracks, and do hereby` declare that thefollowing is a full, clear, and exact description. f

This invention relates to improvements in railway tracks, and theObjectis to provide means whereby a permanent foundation may be laid inthe ground to which the rails may be attached easily and quickly.

The invention relates particularly to the laying of. street railwaytracks, where Ithe In the drawings which illustrate this in-rventionz-Figure 1 is a perspectiye view of the device as it would appearwith all the pavement removed. Fig. 2 is a perspective viewV showing thebond between the sectionsy of the rail chair. Fig. 3 is a crosssectional view of a single rail, showing the method of embedding thesame in the pavement. Fig. 4; is a fragmentary cross sectional view,'showing a slight modification of the invention.

Referring more particularly to the drawings, 5 designates the ties whichmaybe ofwood, but are preferably of metal, `as the life and rigidity ofmetal is greater than that ofwood. Mounted on the ties Iare rail chairs6 having attaching flanges 7, 'similar to the ordinaryrail base flanges.This rail Vchair is comparatively low and webless, the

head 8 rising directly from the flanges. The top of the head is flat andprovided withy the central longitudinal groove 9. This groovelspecifically does not forni one ofthe most importantv features of theinvention, as it may be replaced by a rib 10, shown in Fig. 4, or by anyother suitable means to prevent 'lateral movement of the rail on thechain The rails 11 are of any suitable cross section' and are similartov those in ordinary -use Specification of Letters Patent.

with the exception of a small rib 12 depending from the baseunder theweb. This rib engages in the groove 9 of thechair and prevents lateralmovement of the rail oii the chair. a

In the' forni sho-wn in Fig. 4, this rib is ieplaced by a groove 13,cooperating with .the rib 10 of the chair.

stood that the groove 13 may be of sufficient width to embrace theentire top of the chair, thus eliminating the necessity of a special ofrail is that it may, be laid in the ordinary require recesses formed inthe ties, if the chair was not used. On the other hand, such ribbed typeof rail would be more secure as the rib engaging in the tie would.remove much strainfrom the spikes.'

The preferred method of attaching the chair to the ties is by means ofclamps 14 on the outside of the rails and similar clamps 15 betweenthe'rails. These latter clamps 15 extend from rail to rail and also formdistance bars. These clamps overlap the flanges of the rail chair andare secured to the ties by bolts or'spikes 16. As the rail chair is notof suitable form for the use of fish plates to connect the varioussections,

one end of each member is provided with a project-ing tongue 17 ofreduced size, while the opposite end is provided with a recess 18 forthe reception of the tongue of the ad-V rflanges Vat the time that thesame was laid,

with the threaded ends upand projecting a suitable distance above thefoundation 19. The rails which preferably have tlienecessary bolt holesformed in the base flanges thereof are placed in position onthe chair,and secured by nuts 21. The pavement is then completed, f one or morerows of re.- movable` blocks 22 being placed neXt to the rails, wherethe Vpavement is of asphalt or It will be under-V 'rib 10. An advantageof the grooved. type :sov i ioo a like material. If the pavement isentirely of the block type, no special provision Will be required.

Ihen the rails become Worn out, they may be replaced by simply removinga single row of blocks on each side thereof, removing the Worn rail andsubstituting a new one. As the ties and rail chairs are em bedded in thefoundation of the pavement, the entire track foundation becomespractically one piece and integral with the road. Furthermore, thisembedding of the ties and rail chairs protects the same to a very largeextent against decay, so that a single track foundation will outlastmany sets of rails. As it is not necessary to disturb the trackfoundation in any Way nor to gage the distance between the rails inrelaying the track, the same may be accomplished With great rapidity andvvith practically no interruption of traflic.

Having thus described my invention, I declare that What'I claim is Arailway track comprising a plurality of ties, flanged rail chairsmounted thereon, each of said chairs having at one end a Jtongue and atthe opposite end a recess for the reception of the tongue of theadjacent chair, clamps spacing said chairs and securing the same to theties, rails mounted on said chairs, bolts passing through the chair andrail, flanges securing the rails in position and locking ribs on saidchairs and rails to prevent lateral movement of the rails on the chairs.

In Witness whereof I have hereunto set my hand in the presence of tivoWitnesses.
